10-to-minus12

We can consider the power 10-12 from multiple perspectives.  A few of many examples are listed below: Mass of an average human cell (10-12 Kg) Lowest pressure obtained in laboratory conditions (10-12 pascals) Surface area of an E. coli bacterium (6×10-12 m2) Kinetic energy of a D-T fusion neutron (2.26×10-12 joules) Wavelength of gamma rays [...]
